​BASF introduces innovative waterproofing and concrete protection system for wastewater management infrastructures in Japan

  • MasterSeal 7000® CR system offers unique properties based on XolutecTM technology

  • Full protection in highly aggressive wastewater environment

  • Significantly extends the service life and reduces lifecycle cost of concrete structures

Tokyo, Japan – August 6, 2019 – BASF introduces MasterSeal 7000 CR in Japan from its brand Master Builders Pozzolith - a waterproofing and concrete protection system with unique properties that meet the challenges of aggressive wastewater infrastructures, including tanks and sewers.

Anaerobic bacteria in wastewater environments produce hydrogen sulfide which is metabolized by thiobacillus bacteria producing concentrate sulfuric acid on the concrete surface, which can lead to structural damage in concrete. Thanks to MasterSeal 7000 CR, its highly chemical-resistant, crack-bridging membrane not only helps prevent water and acids from damaging concrete and metal structures, but also prolongs the lifecycle of the structures.

Another key benefit of MasterSeal 7000CR is its tolerance to moisture, both in the substrate and in the environment. It can be applied easily by spray or roller and is compatible with humid substrates. In addition, with the system's fast curing properties, it allows contact with water under pressure as early as 24 hours after application at 20 °C, thus reducing application time and enabling fast return to service with minimal downtime.

 "With aging infrastructures and declining workforce in Japan, this unique and performance-proven system can help our customers to protect the durability of their assets and operations without unexpected downtime. MasterSeal 7000 CR has been tested under conditions that simulate those of a real sewer for five years. The results of the test show no significant changes on the properties of MasterSeal 7000 CR", says Nilotpol Kar, Head of Regional Business Segment, BASF Construction Chemicals Asia Pacific.  
MasterSeal 7000 CR can be applied by spray or roller and it is available in two distinctive colors (red and grey) to assist safe application even in environment with poor visibility.

MasterSeal 7000 CR is based on the new BASF's Xolutec technology for durable construction from Master Builders Pozzolith®, which is the result of several years' development work to take a step forward from the current polyurethane (PU) and polyurethane acrylic (PUA) materials. Xolutec technology optimizes the intermolecular interactions between the resin building blocks and creates an enhanced cross-linked polymer network (XPN), enabling unique material properties for multiple solutions that help reduce life cycle costs through longer maintenance cycles."In recent years, demand for cost-efficient construction, maintenance and repair of wastewater treatment infrastructure is growing unabated in the region", says Takahiro Ikeda, Head of Construction Chemicals, BASF Japan Ltd. "With MasterSeal 7000 CR, the performance-proven system can help our customers address the issues of challenging technical environments."

MasterSeal 7000 CR has a very low odor due to the non-amine base and conforms to Class C and D of Japan Sewage Works Association Anticorrosion Manual, contributing to the work environment and safety of the applicators.

BASF will exhibit MasterSeal 7000 CR at SEWAGE WORKS EXHIBITION'19 YOKOHAMA held at Pacifico Yokohama from Aug 6-9.
